RISThree 2-DOF 1T1R and One 3-DOF 2T1R Full-Hinged Novel Parallel Mechanisms With Zero Coupling Degree and Motion Decoupling: Design and Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the design and analysis of a family of full-hinged partially-decoupled novel parallel mechanisms (PMs) featuring one/two translation(s) and one rotation (1T1R/2T1R). First, three 2DOF 1T1R and one 3DOF ...
Performance Analysis and Optimal Design of a Novel Schöenflies-Motion Asymmetric Parallel Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Since previous studies of parallel mechanisms (PMs) have tended to favor symmetrical overall configuration to obtain relatively stable kinematic and dynamic performance and to satisfy isotropic requirements. The analysis ...
A Translational Three-Degrees-of-Freedom Parallel Mechanism With Partial Motion Decoupling and Analytic Direct Kinematics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: According to the topological design theory and the method of parallel mechanism (PM) based on position and orientation characteristic (POC) equations, this paper studied a three-degrees-of-freedom (3-DOF) translational PM ...
A New Method for Motion-Decoupling Identification of Parallel Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Motion-decoupling identification (MDI) for parallel mechanism (PM) is a significant issue in the analysis and design of PMs. In general, people use the Jacobian matrix method to determine whether a given PM has motion-decoupling ...
Design and Analysis of a New Non-Parasitic Parallel Mechanism for 2T1R Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two-limb parallel mechanisms (PMs) can have several advantages, such as avoidance of mechanical collision, fairly simple architecture, easy assembly, and large workspace. The paper presents a novel two-limb three-degree-of-freedom ...
Composition Principle Based on Single-Open-Chain Unit for General Spatial Mechanisms and Its Application—In Conjunction With a Review of Development of Mechanism Composition Principles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on the general degree-of-freedom (DOF) formula for spatial mechanisms proposed by the author in 2012, the early single open chain (SOC)-based composition principle for planar mechanisms is extended to general spatial ...
